  • Patent number: 12257156
    Abstract: The present disclosure relates to an animal knee joint implant that reflects an anatomical structure of an animal. More particularly, the present disclosure relates to an animal knee joint implant that reflects the anatomical structure of an animal, wherein the knee joint implant is capable of being used for diseases, which are accompanied by bone loss, damage to surrounding muscles, ligaments, and the like and are thus more complex than general knee joint diseases such as rheumatoid arthritis and degenerative arthritis, and wherein the animal knee joint implant is capable of reinforcing stability against varus and valgus as well as stability against flexion and extension, and capable of easily complementing gaps that may occur when the bones of a joint are cut.

  • Patent number: 12251315
    Abstract: A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.

  • Patent number: 12220323
    Abstract: A joint spacer has first and second endplates, with each having a bone engaging surface, and at least two cams with an inclined cam surface positioned on an opposite side. First and second slides, each having ramps with an inclined surface are engaged with the cams of the endplate. The first slide has an angled portion at an end, and the second slide has a hinge portion. A threaded shaft has a hinge portion connected to the slide hinge portion, connecting the shaft to the slide, enabling the shaft to pivot. A nut is threaded to the shaft, and can contact and interfere with the angled portion of the first slide to drive the first slide with respect to the second slide. This results in engagement of the cams and ramps to drive the endplates apart to increase the spacer height.

  • Patent number: 12213895
    Abstract: Embodiments comprise a breast prosthesis. The prosthesis includes a body and a set of straps. In some embodiments, the body is comprised of a cover, on which the straps are disposed, and internal components. The straps connect the body to the person's undergarment in such a way that doesn't need sewing to the undergarment itself. The straps also hold the prosthesis in place, such that it doesn't shift or move, or does so very minimally. A person can use their own bra or similar garment of their choosing, instead of having to purchase a special mastectomy bra.

  • Patent number: 12193926
    Abstract: A size adjustable cover used for soft tissue reinforcement which is adapted to envelop an implantable device, such as a breast implant, in a surgical application. The cover is formed using a circular two-dimensional implantable matrix material having an inner circle and a plurality of fringes which radiate circumferentially from the inner circle. The implantable device is positioned upon the inner circle, and the plurality of fringes are folded inwardly to form an overlapping implant pocket which envelops the implantable device. Each fringe further has a punched opening, allowing a loop of suture thread to link each fringe together. Certain fringes are excluded from the loop to create stabilization tabs which radiate from the inner circle and are attached to a site of host implantation to stabilize the cover and the implantable device within.
